2-D honeycomb MI wave communication system
Published 2014-12-01“…To realize the high reliable communication and the wireless power transmission in the wireless underground sensor network,a new type of 2D honeycomb magneto-inductivenetwork was put forward at VLF band.The system model was established,and bandwidth,group velocity and beam forming technologies were researched based on the cur-rent dispersion equations.Simulation with Runge-Kutta method was carried out to verify the efficiency of the network.The result show that the omnidirectional propagation can be realized in the proposed honeycomb network with more bal-anced bandwidth and group velocity in every direction compared with the square lattice structure.Directional communi-cation can also be realized based on the cooperative multi-antenna technology.The proposed honeycomb mag-neto-inductive network is very suitable to build wireless sensor networks with high connectivity and power efficiency in the underground environments.…”

Adaptive transmission scheme of generalized multi-carrier system based on orthogonal transformation
Published 2012-10-01“…A joint adaptive hybrid single-carrier transmission scheme of orthogonal transformation mode and modulation and coding scheme(MCS)was proposed for orthogonal transformation generalized multi-carrier system(OT-GMC).The scheme achieved the maximal spectrum efficiency by adaptive switching the orthogonal transformation mode and MCS according to effective SINR.When identical transformation was used,the data of each sub-band could be transmitted adaptively and independently.As a result,the spectrum efficiency could be improved.When DFT was used,the signal had lower PAPR and it improved the efficiency of power amplifier.Essentially,this transmission scheme obtains the most optimum compromise performance of spectrum efficiency and PAPR in single-carrier hybrid transmission system.The simulation results show that the presented scheme is better than the single transmission scheme in the aspect of throughput performance.…”
